Raspberry Pi OS Image

Raspberry Pi OS Lite with pre-installed Web 2.0 Mash software

Many questions we receive regarding the Web 2.0 Mash software are actually general questions about GNU/Linux or Raspberry Pi OS (formerly Raspbian).

To minimize questions of this type in future we now provide a custom image with Web 2.0 Mash software preinstalled. Fortunately free software gives us the ability to do so.

It has been tested with Raspberry Pi Zero W, Raspberry Pi 3 and 4. The Raspberry Pi Zero W is completely sufficient.

Features

Based on the official RaspiOS image.
Headless system without a graphical user interface.
Serial console enabled.
Readonly root-fs with remount on demand by Web 2.0 Mash.
Using this method it will be possible to power off the device by simply disconnecting the mains supply.
Shortcut commands ro and rw to switch between ro- and rw- root-filesystem.
Tested with all sensors and actuators supported by Web 2.0 Mash.
Web 2.0 Mash software pre-installed.
Secure-Shell Server enabled.
Network configuration on FAT partition therefore also configurable using a Windows PC.

Preferences

No network interfaces enabled.
Standard Raspbian credentials (please change password!).

Installation

Copy the image file to SD card using

the classic Unix way with dd:

dd if=theimage.img of=/dev/mmcblk0 status=progress

or Raspberry Pi Imager

Configure the Network

Customise the interfaces file in the network directory on the FAT partition:

WLAN enabled:

# uncomment to enable WLAN
auto wlan0

# uncomment to enable wired Ethernet
# auto eth0

iface eth0 inet dhcp

iface wlan0 inet manual
        wpa-driver wext
        wpa-roam /boot/network/wpa_roam.conf

iface dhcpif inet dhcp

Ethernet enabled:

# uncomment to enable WLAN
# auto wlan0 

# uncomment to enable wired Ethernet
allow-hotplug eth0

iface eth0 inet dhcp

iface wlan0 inet manual
        wpa-driver wext
        wpa-roam /boot/network/wpa_roam.conf

iface dhcpif inet dhcp

If WLAN is selected it is required to edit access data in file wpa_roam.conf in directory network.

Initial boot to adapt the system to the size of the SD card and switch to readonly mode.

This may take 5-7 minutes!
